Answer:
33.634 ; 134.536 ; d = √[(50t)² + (45t)²]
Step-by-step explanation:
Given the following :
Toyota Prius = East at 50mph
Dodge Circuit = South at 45mph
Distance apart after 30 minutes :
Distance = speed * time
Distance moved by Prius = ( 50mph × 0.5hr) = 25 miles
Distance moved by Circuit = ( 45mph × 0.5hr) = 22.5 miles
Hence Displacement after 30 minutes :
d = √(25² + 22.5²)
d = √625 + 506.25
d = √1131.25
d = 33.634 miles
Distance apart after 2 hours :
Distance = speed * time
Distance moved by Prius = ( 50mph × 2hr) = 100 miles
Distance moved by Circuit = ( 45mph × 2hr) = 90 miles
Hence Displacement after 2 hours :
d = √(100² + 90²)
d = √10000 + 8100
d = √18100
d = 134.536 miles
Distance d in miles after t hours :
d = √[(50t)² + (45t)²]
Answer:
d=45t
Step-by-step explanation:
to find speed you divide the distance by the time. 67.5/1 1/2 = 45
Answer:
Step-by-step explanation:
5 x 6:30
Answer:
She spent 4/6 of her free time.
Step-by-step explanation:
1/6 + 3/6 = 4/6
.35 is the answer because when you write it as a fraction
7/20we know that 20 equals 100we get 100by multiplying 20 by 5 do you just multiply 7by5 which equals 35 over 100 which equals .35.please follow me on brainly
